Long range acoustic Intruder solutions

The Long Range Acoustic Device (LRAD) is an acoustic hailing device developed to send messages, warnings, and harmful, pain inducing tones over longer distances than normal loudspeakers. LRAD systems can be used to counter piracy, as non-lethal crowd control weapons, and as communication devices. LRAD systems are used by maritime to send instructions and warnings over distances, and to force compliance. LRAD is also used to deter wildlife from airport runways, wind and solar farms, nuclear power facilities, mining and agricultural operations and other industrial facilities.
